I have some clarifications please

form1.windowstate=maximized
form1.text="FORM-1 TEXT"

and in mdi-parent as form-2

form2.windowstate=maximized
form2.text="FORM-2 TEXT"

My Problem is when I click on ToolStripMenuItem it's displaying like the following

1-line "Form-1 Text"
2-line "Icon & Maximize & Minimize & Control Box buttons"
3-line "Toolstrip-1"
4-line "Tollstrip-2"

How to avoid this 2nd line?

I am not exactly understanding what you are stating here. Are you saying you would like to remove one of the items that your ToolStripMenu has?

When you click on ToolStripMenuItem it is displaying that text? How is it displaying it? Are you stating that is being displayed during Execution or in the windows form designer?

Hi Seen,
Well & thanks for your reponse. Now I found the answer.It may be useful to someone like me.

Actually Iam trying to display the mdichildren forms, from mdiparent-form's-toolstrip DropdownButton.

Answer :-

Form3.MdiParent = Me
Form3.Dock = DockStyle.Fill
Form3.Show()

the above codes displays the mdichildren form as full screen within the mdiparent form.

Ohhhh, I understand what you were asking now.

I am sorry, I didn't understand your question

Happy Coding!!
